DRS/RTSA / Xilinx

“I worked with Jim who was hired as a consultant to assist us with some issues we had encountered trying to communicate with a SCSI-based storage array with some newly designed hardware.  Jim has excellent knowledge of the SCSI protocol.  His experience in storage systems allowed us to debug various issues when we experienced support issues from the storage system vendor.  It was a pleasure working with Jim; his prompt and insightful responses saved a lot of time during our system debugging.  I would gladly work with him again in the future." July 11, 2011

Brett Matthews, Staff Design Engineer at Xilinx (client)


“I have worked with Jim on several projects over the last five years at NetApp and PMC-Sierra. His depth of knowledge of embedded and storage systems is excellent and his ability to see architectural challenges ahead of time helped guide product scope.  Personally, Jim brings a unique view to development and engineering.  His 30+ years of doing everything from detailed product architecture to running his own business has given him great insight. I look forward to working with Jim in the future.” June 7, 2011

Storage Architect / Designer

Apeiron Data Systems

“I had the pleasure of working with Jim at Apeiron. He was responsible for developing the core driver software and helped architect the software / hardware structure for our product with our CTO. He has a number of years of storage experience which was invaluable in making decisions about the trade-offs between software and hardware. His experience with past drive technologies was extremely helpful when considering development alternatives. He also has a wonderful can-do attitude and works without direction. Once he has a rough definition of what is needed he independently works whatever hours are needed to get a working prototype. He is a hands-on engineer who writes software but is comfortable working directly on hardware as needed to test his code. From his prototypes the team was able to optimize the final architecture using a working model. He works hard to make sure his code was bug free and working upon delivery and was critical to system bring-up efforts with our actual systems. His code was always written in a way that facilitated our system debug. He was never in the critical path for our development. His documentation is always complete and his code is commented clearly - unusual for most developers. Jim is also a quick study when working on new operating systems and was able to develop driver versions for Centos, Suse, and Ubuntu when he was asked to. He is an inquisitive, thoughtful engineer who likes to see his work used in actual products. I would highly recommend him for driver development and working on software stacks relating to storage, particularly NVMe. Feel free to reach out if you have questions.”

Lee Harrison, CEO (manager)

“Bottom line, I’ve never worked with a more talented SW developer throughout my 35 or so years in technology.  Very grateful to have had the opportunity.”
April 2, 2017

Bob Hansen, Vice President of Solutions Architecture (colleague)

“Jim is in charge of the driver development for Apeiron’s NVMe storage products. He is very knowledgeable when it comes to storage, NVMe in particular, and writing high performance software in general. The main focus has been on the Linux driver and Jim architected his driver so that it is easy to port to other platforms such as VMware ESXi and Windows Server. He is also interested in exploring the next generation technologies and upcoming products and helping the company adopt such technologies. I would enjoy working with Jim again in the future..March 22, 2017

Dragos Harabor, Director of Storage Software at Apeiron Data Systems (colleague)


“I worked with Jim for approximately two years at NetApp. During that time he demonstrated superior technical leadership and a quick wit.  Jim was always fun to talk to, and not just on technical topics, and hence I was sorry to see him leave for other opportunities.” June 7, 2011

Radek Aster, Sr. Software Engineer, NetApp (colleague)

“Jim has great experience in the storage industry.  I worked with Jim at NetApp where he led the team in architecture and design.  He always provided useful insight to our challenges and suggested pertinent solutions.  Jim had a unique perspective, having built and sold a product from the ground up that helped round out the team.  Jim is easy to get along with and I enjoyed working with him.” June 7, 2011

Todd Mills, Senior Software Engineer, NetApp (colleague)

“Jim is a highly experienced storage professional with years of industry experience.  In his position at NetApp reporting to me, Jim was responsible for several different from-scratch storage subsystem development efforts in which he provided technical direction, directed the work of other members of the engineering team, and designed and wrote code of his own as well.  Jim knows the storage "universe" very well and can be counted on to have relevant knowledge and experience as a consultant to any project in that space.” June 6, 2011

 “Jim has successfully established two companies. At Kolinar, he both implemented and coded software products designed to run under VM/370. At Ark Jim mostly coded from scratch a PC operating system and applications which permitted all sorts of disk performance and reliability improvements. Kolinar was sold to another company and the software Jim developed at Ark was sold to a 3rd party. Jim had to leave Ark to support the Ark product. After over 30 years developing and fixing software, I can truly say that Jim is the most insightful and intelligent programmer I have ever met.” April 24, 2008

Kolinar / VM Systems Group

“Jim is both a creative programmer and a highly analytical thinker. At Kolinar he managed the technical and management ends of the business with equal aplomb -- and success. As an advocate for the users, I typically came to Jim with one of two things; a request for enhancement or a bug. With bugs, his intense pride of ownership in the software catalyzed him to fix problems faster than I've ever experienced with a software company before or since. As for suggestions, his metric, which I have used many times over the years, was "If I add this feature, will we sell more copies?" Faced with a problem or decision, Jim has the ability to absorb a huge amount of information and then rapidly synthesize and take action appropriately. Beyond his intellect, he is a funny guy which made for a comfortable work environment.” May 26, 2008

James Weissman, Director of Marketing, Kolinar Corporation
reported to Jim at Ark Systems, Inc. (California)

 “Jim is one of the few managers with a full perspective of the likely issues his team will encounter during software development projects. His knack for being there with guidance at the most appropriate time is uncanny, to say the least. He is also a detail oriented engineer who never overplays his role as a project leader; consequently, his team mates willingly do their best to reach project goals. Jim is an extremely well rounded senior executive and especially adept in "start-up" ventures.” May 16, 2008

Chuck Brown, Owner, CHBI
worked directly with Jim at Kolinar / VM Systems Group

“There are no stereotypes to describe Jim, a totally unique individual, for whom I would work for again. Jim is a first-principles thinker who is able to focus his startling intellect on any complex issue and reduce it to shreds. He is unfailingly humble and sincere for a person with so much deep insight into the world. He has an incredible attention to detail which results in everything he does being of an exceptionally high quality. He passed this ethic on to me in both word and deed and made me realize what it takes to produce a software product - versus a hack. Once he has thoroughly digested categorized and stored all detailed knowledge on a subject he puts a plan into action which is seen through to the end. Jim has tremendous insight into many diverse and interesting subjects. I have learned more about UK culture from Jim than growing up there. Some of my fondest memories are when I heard him play a note-perfect rendition of Genesis' Duke and when he took me along on a lunchtime excursion to buy a Fairlight.” April 29, 2008

Adrian Blakey, Director of Applications Development, Kolinar Corporation
reported to Jim at Kolinar / VM Systems Group

“I first met Jim Bergsten when VM Systems Group and Kolinar merged into one company. I was tasked with packing and moving the Kolinar assets from California to Virginia in just three weeks. As President and CEO of Kolinar, Jim was my main point of contact. He was intelligent, thoughtful, approachable, and very easy to work with during this daunting task. He was perceptive and supportive, knowing when to step in to help and when to step back and let me do my job. After merging the two companies, Jim brought his knowledge and expertise to the Board of Directors’ planning table and played a vital role in helping the company to expand sensibly and profitably. Not only were his technical skills stellar, but he thoughtfully reached out to peers and subordinates alike, allowing them input into the direction that Software Development should take, thereby enabling them to feel invested as stakeholders. This team-minded approach helped his Research and Development group identify and prioritize a variety of development projects, to help build a compelling roadmap, guiding the company to the next level and increased profitability. The quality and professionalism of his efforts coupled with his integrity were quite impressive. As I was just beginning my career in the software development field, Jim encouraged me (and others) to pursue more challenging, complex projects that helped us become better and more productive employees. If we weren’t living on opposite coasts, I would definitely find a way to work with Jim again.” April 24, 2008
